Black Mouth Curs are medium to large-sized dogs. Their breed has a wide weight and height range. Males tend to be larger and heavier than females of a similar lineage, with broader chests and more muscular builds.
According to the United Kennel Club (UKC ), the minimum weight and height standard for males is 40 pounds and 18 inches at the shoulder, and the minimum for females is 35 pounds and 16 inches at the shoulder. The range for males is typically a height of 18 to 26 inches at the shoulder and a weight of 40 to 90 pounds. Females usually have a height of 16 to 24 inches at the shoulder and can weigh 35 to 80 pounds. This wide size range reflects the various lines of Black Mouth Curs found throughout the southern U.S. that have been selected for diverse traits and characteristics.
